What is the equation of the following graph in vertex form? the graph shows a positive parabola with the vertex at, (-1,0) and passes through (0,1) and (-2,1) answers y = (x − 1)2 y = (x − 1)2 + 1 y = (x + 1)2 − 1 y = (x + 1)2

Vertex form uses the following formula:

a determines the stretch of the parabola. h and k are the x and y values of the vertex (h, k), respectively.

The vertex is at (-1, 0). There is no a value indicated for any answer. Plug these values into the equation:

The answer is (x+1)^2.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
